News on the escapeeeeeeee

Police believe:
He acted alone
He's still in Singapore
(Link from here)

If he had acted alone, how is it then so easily for him to escape from a prison toilet?
What's more, the prison has high security system in place(or so they say).

If it is true, then there's 2 possibilities:

1. He is damn good, damn goood
2. Our security has loop holes(remember the Hua Na kidnapping incident? Ah Hao also escaped from toilet.)

Aiyoh, 2 more days would be a week since he has gone missing.
This issue is just like the kidnapping case, the longer it takes to find the missing person, the slimmer the chance of apprehending the culprit. In this case, it would be harder to find the escapeeeee.

How ah?
I can't wait for him to be caught and then he will finally reveal where he has been hiding, if he is alone and importantly, how did he escape?
